Grand Theft Auto III

Weapons are bought by walking over a floating weapon pickup inside Ammu-Nation stores. When the player enters the store, the camera switches to a fixed position at the corner of the store until the player exits the store. The clerks carry Shotguns and will attack the player if the player is aggressive.

Ammu-Nation seems to have connections with Mr. Black and his contract killing company, since during a mission in GTA Vice City, protagonist Tommy Vercetti is hired to kill a business man, steal a briefcase he's carrying and deliver it to the owner of an Ammu-Nation local in Downtown.

Grand Theft Auto: San Andreas

Weapons are bought by standing on the red marker inside Ammu-Nation stores. A menu to choose the weapon is displayed. The player can preview the weapon by selecting the weapon without buying it and the clerk will bring up the weapon to display. Ammu-Nations only open up after the mission Doberman. All clerks dual wields Pistols.

There is an unused Ammu-Nation interior in San Andreas. It has two floors and can only be entered using certain cheats or with cheat devices. The store is functional if entered properly.

Grand Theft Auto Advance

Weapons are bought by standing on the marker in front of Ammu-Nation stores. The game pauses and a menu appears to let the player purchase weapons. The store itself cannot be entered so no clerk appears in this game.

Grand Theft Auto: Liberty City Stories

The Ammu-Nation stores in GTA Liberty City Stories functions similar to GTA III. The player will buy the weapons by walking into the yellow marker. Just like in GTA III, the same fixed camera view returns which makes the players unable to use first person view weapons like Sniper Rifle or Rocket Launcher. Clerks carry shotguns and will attack the player if aimed at or the player fires a weapon inside the store.

Grand Theft Auto: Vice City Stories

The Ammu-Nation stores in GTA Vice City Stories functions exactly the same as in GTA Vice City. But all clerks inside the stores carry Shotguns similar to GTA III and Liberty City Stories. The cost inside the parenthesis is the discounted price of the weapons after completing Phil's Shooting Range.

Grand Theft Auto: Chinatown Wars

In Grand Theft Auto: Chinatown Wars, Ammu-Nation is a website which the player can order weapons from. These are delivered to safehouses. Though no actual stores are seen, trucks are driven around Liberty City and often contain weapons.

Shooting Ranges

Shooting ranges can be found in some Ammu-Nations throughout the GTA III series. These places test your skill in handling your weapons.

Commercials

Ammu-Nation radio commercials make it clear that the store is run with with a right-wing paranoia philosophy, describing itself as the "store leading the fight against communism". The store also seems to promote the purchase of its products for illegal purposes, even suggesting they be used to kill one's mother-in-law if she is "being a bitch".
